I've got a TB and both of the coolant nipples are horrible and rusted. Is there any way to replace these or do I just need to look for a replacement TB? I searched around on here and google and didn't find anything, but maybe I'm just not looking for the right term. Thanks.

 

In my opinion it wouldn't be worth it to replace them since finding a TB is pretty easy and cheap... or you could just bypass them all together, they're pointless anyway.

 

Whats the easiest way to bypass it? I still have my bac and don't want to remove it. What does the coolant going through the TB do?

 

Not pointless. It operates the thermowax in the throttlebody that keeps the throttle plates open while your car warms up.

The coolant hose on the BAC is uncessecary (at least in FL) though. It just helps warm it up quicker in very cold conditions. I removed the BAC coolant line and ran the TB coolant line straight to the nipple on the back to the WP.

 

I had a problem after my rebuild with those nipples constantly cracking and breaking (causing me to take off the upper manifold to repair it AGAIN AND AGAIN). So after I got fed up with one enough I just used a short piece of coolant hosing and blocked it off a bolt some rubber sealer and a hose clamp. After that the pressure of the radiator system no longer gave me any problems. I would like to note I did this as a last ditch effort to stop having coolant sprayed all over my engine bay

 

This is correct.
